No. 3047:

To clarify, Lenny hasn't come back to life yet. He's still technically dead...

... which is why he does not appear in this strip. Ha! True Postcard fans can tell that the tall-haired man shown here is an impostor, because he has an actual character alignment. However, he's only staying dead until the animated adaptation. Which won't be for quite a while, since the Kickstarter for it - which we happily invested half a year into planning out - never raised enough money.
